assume the data

Your environmental chemistry professor asks you to make a 1-L solution with a calcium ion activity of 1.3 x 10-4 in 0.06 M KCl at 20 C. You know the activity coefficient for a 0.06 M KCl solution is 0.462, from a previous homework. a. (5 pts) How many moles of CaCl2 do you need to make the 1-L solution? b. (5 pts) Would you need more or less CaCl2 to make a solution of the sam activity in distilled water? Explain
